A system and method for determining soil properties, such as organic matter (OM), pH, and electrical conductivity (EC) using a mobile soil sample station and a multispectral sensor mounted on a multi-rotors or professional fixed-wing drone. Combined with an optional fixed soil sampling station and mathematical modeling (built with Cloud-based database with iterative learning process) calibration, the system and method improve soil analysis by enabling real time examination, as well as improving affordability and efficiency.
